Abstract
Background: Percutaneous transcatheter angioplasty (PTA) and carotid artery stenting (CAS) are often performed repeatedly for in-stent restenosis (ISR) after CAS. Only a few reports describe the treatment for repeated ISR. Furthermore, only a few reports describe carotid endarterectomy (CEA) after CAS; thus, the evidence for this procedure is insufficient.
Case Description: Herein, we describe a case in which CEA with stent removal was performed in a patient with repeated ISR after CAS. A 78-year-old man presented with dysarthria and slight left limb weakness. CAS was performed for the right internal carotid artery stenosis. ISR occurred again and PTA and stenting were performed. After the second CAS, ISR occurred again. CEA with stent removal was performed. After the CEA with stent removal, the patient experienced no restenosis or other complications.
Conclusion: CEA with stent removal can be a good option for treating repeated ISR after CAS.

INTRODUCTION
The rates of in-stent restenosis (ISR) after carotid artery stenting (CAS) are between 3% and 10% and ISR is associated with ipsilateral cerebral infarction.[
CASE REPORT
A 78-year-old man with hypertension, Type 2 diabetes mellitus, and dyslipidemia presented with dysarthria and slight left limb weakness. Diffusion-weighted imaging revealed multiple small cerebral infarctions spreading cortically and a watershed area in the right brain hemisphere [
Figure 1:

CAS was performed 1 month after symptom onset. Although a staged CAS was planned, plaque protrusion occurred just after PTA; therefore, we deployed a closed-cell stent (Carotid WallStent 10 × 24 mm, Boston Scientific, Marlborough, MA, USA) [
Figure 2:
(a) After carotid artery stenting (CAS), the postoperative carotid echography revealed no stenosis. The peak systolic velocity (PSV) was 62.3 cm/s. (b) A carotid echography 4 months after the first CAS showing in-stent restenosis (ISR). The PSV was over 300 cm/s. (c) Angiography showing ISR 4 months after the first CAS. (d) The angiography after percutaneous transcatheter angioplasty and a second CAS were performed.
Six to 9 months after the second CAS, ISR again worsened; the carotid echography revealed a PSV of 139–317 cm/s [
Figure 3:
Worsening in-stent restenosis (ISR) after the second carotid artery stenting is shown. The carotid echography revealed peak systolic velocity changes from 139 cm/s (a) to 317 cm/s (b) 6 to 9 months after the second carotid artery stenting. (c and d) The angiography shows severe ISR. (e) The distal end of the stent location at the C2 level is shown.
Figure 4:
(a and b) The clear boundary between the plaque, including the stent, and the vessel wall is shown. Normal carotid endarterectomy was performed. (c) Insertion of an internal shunt after removed plaque is shown. (d) The vessel wall could be sutured as normal. (e and f) The stent and plaque are shown. Neointima formed inside the lumen of the stent, causing in-stent restenosis.
DISCUSSION
ISR is a complication that may occur after CAS. Cases of symptomatic or severe restenosis may require retreatment. The rate of cerebral infarction onset on the same side after CAS was 6.6%/3 years in the SAPPHIRE study,[
ISR has three primary causes. First, early postoperative stenosis with plaque protrusion or thrombus on the stent can cause ISR. Second, neointimal hyperplasia caused by non-specific inflammatory responses of blood vessels to the chronic mechanical stimulation of stents can cause ISR.[
CONCLUSION
Conclusions about the optimal intervention for ISR cannot be made yet; however, CEA with stent removal is another good option.[
Our case required repeated treatment for ISR. After a careful discussion about the optimal treatment, we decided to perform CEA with stent removal after the third occurrence of ISR. If a third CAS had been performed, the lumen might have narrowed because of the thickness of the stent itself and ISR might have reoccurred. CEA was problematic for this patient, because of inadequate collateral flow, and insertion of an internal shunt was needed. The distal end of the stent was at the C2 level, and we were unsure if the space would be adequate for insertion of the internal shunt. As a result, CEA was carried out 13 months after the second CAS.
The structure between the intima and media is maintained because the carotid stent is located inside the intima. In earlier studies, a few perioperative technical difficulties for CEA with stent removal were reported.[
